VENTING REQUIREMENTS
Determine which venting method is best for your application. Ductwork can extend either through the wall or the roof.
The length of the ductwork and the number of elbows should be kept to a minimum to provide efficient performance. The size of the ductwork should be uniform. Do not install two el- bows together. Use duct tape to seal all joints in the ductwork system. Use caulking to seal exterior wall or floor opening around the cap.
Flexible ductwork is not recommended. Flexible ductwork creates back pressure and air turbulence that greatly reduces performance.
Make sure there is proper clearance within the wall or floor for exhaust duct before making cutouts. Do not cut a joist or stud unless absolutely necessary. If a joist or stud must be cut, then a supporting frame must be constructed.

WARNING - To Reduce The Risk Of Fire, Use Only Metal Ductwork.
!WARNING
•Venting system MUST terminate outside the home.
•DO NOT terminate the ductwork in an attic or other enclosed space.
•DO NOT use 4"

WARNING - TO REDUCE THE RISK OF FIRE, ELECTRI- CAL SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING: Installation Work And Electrical Wiring Must Be Done By Qualified Person(s) In Accordance With All Applicable Codes And Standards, Including
Sufficient air is needed for proper combustion and exhaust- ing of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturer's guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.
When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
Ducted fans must always be vented to the outdoors.
!WARNING
•Electrical ground is required on this rangehood.
•If cold water pipe is interrupted by plastic, nonmetallic gaskets or other materials, DO NOT use for grounding.
•DO NOT ground to a gas pipe.
•DO NOT have a fuse in the neutral or grounding circuit. A fuse in the neutral or grounding circuit could result in electrical shock.
•Check with a qualified electrician if you are in doubt as to whether the rangehood is properly grounded.
